Whateversaurus

A lot of works are set in One Million BC. However, some works just do a few episodes in prehistory, while mostly in other eras. When this happens, they usually have a prehistoric animal be an ancestor of the characters in the show.

However, most writers only know a few types of dinosaur. When they don't think they can pass off any of them as the ancestor of their character, they tend to use either "Xsaurus", "Saber-toothed X", "Xdactyl", "Xrex", "Xraptor" or "CaveX". May also sometimes occur in modern-day set dramas involving mutated animals.

Funny Animal characters are usually neanderthals unless they are antagonists.

Note that this includes both portmanteaus or mix and match critters of a modern-day animal and a prehistoric animal. May intersect with Artistic License – Paleontology. Related to Dire Beast.

    Comic Books 
  • The "Cave Cat" segment of Garfield: His 9 Lives shows Garfield as a saber-toothed housecat and Odie as a giant green saber-toothed dog.
  • In one of Atomic Robo's Free Comic Book Day issues, Dr. Dinosaur manages to make a cyborg Tyrannosaurus that he dubs a "Futuresaurus Rex".
    • In a later FCBD issue, he makes a killer "Omnisaur" out of a Triceratops, Ankylosaurus, and Stegosaurus.
      Robo: Aren't those herbivores?
      [Beat]
      Dr. Dinosaur: [to Omnisaur] You were supposed to tell me everything!
  • An 1975 underground comic "Valley of the Dildosaurs" (NSFW - duh), parodying all the Dino movies (of course mainly "Valley Of The Dinosaurs"), even goes on a lampshading tangent: "Yes, we know that Hornysaurus and Vibratodon never lived at the same time!"

    Film 
  • A number of Syfy movies. Case in point: Dinocroc.
  • Insectosaurus from Monsters vs. Aliens.
  • The film version of A Sound of Thunder has baboonasaurs, flying batboonasaurs & the claim that lions are descended from allosaurs.
  • The plot of Jurassic World sees the park shift from reviving known dinosaurs to engineering one of their own, called Indominus Rex.

    Literature 
  • After Man: A Zoology of the Future has saber-toothed weasels and monkeyraptors
  • Man After Man: An Anthropology of the Future has saber-toothed humans and ground slothmen.
  • The book "Science Made Stupid", a parody of children's science books, has a Puppisaurus in a sidebar about mammal-like reptiles (the group did exist, albeit as a group of animals increasingly closely related to true mammals, but it didn't include a Puppisaurus).
  • Similar puns fill up the out-of-print children's book, "Dodosaurs: Dinosaurs That Didn't Make It".

    Live Action TV 
  • In Power Rangers Time Force, the Quantum Ranger had a dinosaur mecha called the Quantasaurus Rex, or Q-Rex for short. The Mirai Sentai Timeranger version was simply the V-Rex. Power Rangers Megaforce would later recycle the Q-Rex name for its dino mecha in homage to the original.
  • Power Rangers Dino Thunder called its main mecha combination the Thundersaurus Megazord.
    • One episode also had the Rangers' class at a paleontology dig, and when Kira tried to get Dr. O's attention she claimed that she found a "morphasaurus" fossil.
    • Dino Thunder's counterpart does a similar play on the Japanese word for dinosaur(s), "kyoryu"; calling their dino-like mecha "bakuryu" ("blastosaurs").

    Newpaper Comics 
  • The title panel of this Garfield strip has Odie as a Dogasaurus.

    Video Games 

    Web Original 

    Western Animation 
  • The Flintstones sometimes makes vague references to creatures like a "chickensaurus"
  • Scrat from Ice Age is a saber-toothed squirrel. However, he is actually based on Leptictidium.
  • The Future Is Wild features a saber-toothed wolverine, a caracararaptor, and a turtlesaurus (specifically named a snowstalker, carakiller, and toraton).
  • The Looney Tunes short Prehistoric Porky shows Porky to be descended from a cavepig, while Pre-Hysterical Hare shows Bugs to be descended from a saber-toothed rabbit.
  • The Tom and Jerry short "Prehisterics" has Tom as a saber-toothed housecat and Jerry as a cavemouse. During the short they encounter a giant saber-toothed rabbit.
  • The SpongeBob SquarePants episode "Ugh" has Spongebob, Patrick, and Squidward as a cavesponge, caveoctopus, and cavestarfish, with Gary as a giant snailsaurus.
  • Dino Squad has many examples. Most of the mutated creatures created by Victor Veloci were mutated mixes of modern day and ancient creatures. Only the Dino Squad were 'perfect' creatures.

    Real Life 
  • In reality, many prehistoric animals seem like this. For example, ceratopsids (rhinosauruses), sauropods (giraffesauruses), pterosaurs (batsauruses), ichthyosaurs (dolphinsauruses), ornithomimids (ostrichsauruses), spinosaurids (crocodilesauruses), Dinofelis (saber-toothed leopard), etc. Subverted since they aren't ancestors of the similar modern-day creatures.
  • Some prehistoric creatures are named this way (but the X part is almost always in another language), such as Nanuqsaurus (polar bear lizard) and ichthyosaurs (fish lizards). An interesting aversion is Struthiosaurus, which means "ostrich lizard" but looked like this.
  • Reptiles filmed using perspective tricks to look like giant monsters are nicknamed "Slurpasaurs".
